8.2.10 Secured 32-bit data
When the following conditions, 1) and 2) are satisfied in the CC-Link network, 32-bit
data in remote registers (RWr/RWw) between a programmable controller CPU and a
master/local station can be secured.
1) Access starts from a remote resister (RWr/RWw) address of an "even number".

Because the start address on the remote resister
side is an "odd address", new and old data may be
mixed in 16-bit (1-word) units.
2) Access by the program must be made in units of even points.

Because the access is made for each single point
(1-word), new and old data may be mixed in 16-bit
(1-word) units.
